WallJax creates an oscillating magnetic field in a coil called the "transmitter coil," which induces a current in the "receiver coil" in the phone.
mpi signal is derived from the non-linear re-magnetization response of the particles in the oscillating magnetic field.
We have developed an implantable system that can provide on-demand, reproducible drug release whenever the patient - or other operator - wants, for as long as needed, and with the intensity that is desired, using a trigger that is external to the body - in this case an oscillating magnetic field," Daniel Kohane told Nanowerk Spotlight Journal.
An oscillating electric field generates an oscillating magnetic field, and an oscillating magnetic field generates an oscillating electric field.
An oscillating magnetic field produces an electrical field, and when oscillated at the proper frequency (1 Hz/sec), that electrical field can produce prolonged depression of excitability of the brain cortex.
Because an oscillating magnetic field generates an oscillating electric field, and vice versa, the two fields sustain each other as the wave propagates.
An oscillating magnetic field at the correct frequency can make nuclei change from low- to high-energy states.
Reduce bacteria in the food and allow it to keep longer by pulsing the food with an oscillating magnetic field during storage--allowing the products to be kept for two to three years, or even longer.
The most versatile approach appears to be incorporating ferromagnetic particle "tags" whose vibration in an oscillating magnetic field can reveal the "health" of a composite.
Using a slowly oscillating magnetic field, the researchers can force the ribbon to droop and straighten in sync with the field.
mpi signal is derived from the nonlinear response of re-magnetization of the particles in the oscillating magnetic field.
The idea, Langer explains, is that "when you turn on an oscillating magnetic field, the beads will move and actually squeeze pores that contain our drug, allowing it to come out.
